                        SuSE Security Announcement

        Package:  INN 2.0 and higher
        Date:     Wed May 19 15:20:33 CEST 1999

______________________________________________________________________________

Some security holes were discovered in the package mentioned above.

There is no warranty whatsoever and no liability for any direct, indirect or

______________________________________________________________________________

1. Problem Description

    The innd wrapper inndstart could be tricked to execute arbitrary
    code by editing the environment (INNCONF), by modifing the inn.conf
    file or by overflowing a buffer.

2. Impact

    As long as /usr/lib/news/bin/inndstart is SUID root a attacker
    could gain local root access to your system.

3. Solution

    Remove the SUID bit of inndstart by executing
      /bin/chmod 700 /usr/lib/news/bin/inndstart

    Disallow other users than news to access /usr/lib/news
      /bin/chmod go-rwx /usr/lib/news

    Install a patch (update the package) as soon as the bug is fixed!
